Abstract: The local instability of borehole walls in complex compressible media is studied within the framework of exact three-dimensional equations. Numerical experiments were performed for particular materials. The effect of the dilatancy rate, the viscosity, the gravity parameter, and Poisson's ratio on the critical parameters is estimated.
